It has been accepted for inclusion in Doctoral Dissertations by an authorized administrator of University of New Hampshire Scholars' Repository. For more information, please contact [email protected]. INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with edjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected teat the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in tee adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" tee material. It is customary to begin photoing at tee upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. I f necessary, sectioning is continued again - beginning below tee first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographa" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving tee catalog number, title, author and specific pages you wish reproduced. 5.

THE ECOLOGICAL REQUIREMENTS OF THE NEW ZEALAND FALCON (Falco novaeseelandiae) IN PLANTATION FORESTRY A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Zoology at Massey University, Palmerston North, New Zealand Richard Seaton 2007 Adult female New Zealand falcon. D. Stewart 2003. “The hawks, eagles and falcons have been an inspiration to people of all races and creeds since the dawn of civilisation. We cannot afford to lose any species of the birds of prey without an effort commensurate with the inspiration of courage, integrity and nobility that they have given humanity…If we fail on this point, we fail in the basic philosophy of feeling a part of our universe and all that goes with it.” Morley Nelson, 2002. iii iv ABSTRACT Commercial pine plantations made up of exotic tree species are increasingly recognised as habitats that can contribute significantly to the conservation of indigenous biodiversity in New Zealand. Encouraging this biodiversity by employing sympathetic forestry management techniques not only offers benefits for indigenous flora and fauna but can also be economically advantageous for the forestry industry. The New Zealand falcon (Falco novaeseelandiae) or Karearea, is a threatened species, endemic to the islands of New Zealand, that has recently been discovered breeding in pine plantations. This research determines the ecological requirements of New Zealand falcons in this habitat, enabling recommendations for sympathetic forestry management to be made.

NUMBER 2020 OCTOBER 14, 1960 The Odonata of the Bahama Islands, the West Indies BY MINTER J. WESTFALL, JR.' Through the courtesy of Dr. Mont A. Cazier of the American Museum of Natural History, I have had the privilege of studying a collection of 439 specimens of Odonata from the Bahama Islands. The number of species represented in this collection is not large, and no species new to science has been recognized, but relatively few records are found in the literature for these islands. Much collecting has been done in the Greater Antilles, and they were included in the range covered by the recent "Manual of the Dragonflies (Anisoptera) of North America" by James G. Needham and myself. Elsie B. Klots (1932) presented an excellent contribution on the Odonata of Puerto Rico, including records from the other Antilles, but no similar work has been done for the Bahamas. Klots had begun a preliminary investi- gation of the Bimini material but was unable to pursue the study, so that the entire lot was sent to me. A large number of specimens reported in the present paper were taken between December 31, 1952, and May 13, 1953, by the following members of the Van Voast-American Museum of Natural History Expedition to the Bahama Islands: G. B. Rabb, Ellis B. Hayden, Jr., and L. Giovannoli. The expedition took them to many of the islands from Grand Bahama Island and the Abaco Cays in the north to Great Inagua Island and the Turks Islands in the south.

    Odonatologica 29{1): 67-73 March I, 2000 Micrathyria sympriona spec. nov., a new dragonfly from Ecuador and Peru (Anisoptera: Libellulidae) K.J. Tennessen 1949 Hickory Avenue, Florence, AL 35630, United States Received March 14, 1999 / Reviewed and Accepted June 10, 1999 The Zamora new sp. (holotype 6 , allotype 9: Ecuador, Chinchipe prov., grassy marsh 5.5 km SE of 3000 Zamora, ca ft, 4°10’S, 78°56’W, 5-XI-1997; deposited at FSCA, Gainesville, FL, USA) is described and compared with M. hypodidyma Calvert. M. in sympriona differs the low, laterally rounded transverse ridge on the venter of abdominal segment 1 which bears 0 to 3 widely spaced black denticles on each side of the median depression, the tips of the outer arms of the hamules surpassing the ante- rior laminae, and segment 9 all black. Females have abdominal segment 9 sternite instead of flat in M. convex as hypodidyma. INTRODUCTION Micrathyria is a neotropical group of42 currently recognized species (BRIDGES, 1994), although the genus is in need of revision. Recently described species in- clude ringueleti (RODRIGUES CAPITULO, 1988), venezuelae (DE MARMELS, 1989), caerulistyla (DONNELLY, 1992), and divergens, dunklei, occipita, and pseudeximia (WESTFALL, 1992). DUNKLE (1995) described a new subspecies of mengeri. The new species described here is from southern Ecuador and Peru. When I first looked at the thoracic color pattern and hamulesin the field, I assumed they were M. laevigata Calvert. When J.J. Daigle and Iexaminedthem more closely in noticed different the laboratory, we the very cerci and suspected they repre- sented an undescribed species.

  • Description of the Final Stadium Larva of Erythrodiplax Media (Odonata
    International Journal of Odonatology, 2018 Vol. 21, No. 2, 93–104, https://doi.org/10.1080/13887890.2018.1462260 Description of the final stadium larva of Erythrodiplax media (Odonata: Libellulidae) with preliminary key to known South American larvae in the genus Marina Schmidt Dalzochio a∗, Eduardo Périco a, Samuel Renner a and Göran Sahlén b aLaboratório de Ecologia e Evolução, Universidade do Vale do Taquari – UNIVATES, Lajeado, RS, Brazil; bEcology and Environmental Science, The Rydberg Laboratory for Applied Sciences (RLAS), Halmstad University, Halmstad, Sweden (Received 25 July 2017; final version received 6 March 2018) The larva of Erythrodiplax media is described and illustrated based on two exuviae of reared larvae and one final stadium larva collected in Xangri-lá, State of Rio Grande do Sul, Brazil. The larva of E. media can be distinguished from other species of Erythrodiplax by the presence of lateral spines on S8 and S9, the number of premental setae (n = 22), palpal setae (n = 7) and by the mandibular formula. We also provide a preliminary key to known South American larvae in the genus. Keywords: Brazil; coastal wetlands; dragonfly; exuvia; Anisoptera Introduction Erythrodiplax Brauer, 1868 is an American genus that includes 60 species (Schorr & Paulson, 2017), of which 40 are known to occur in Brazil (Pinto, 2017) and 18 are hitherto reported from the state of Rio Grande do Sul (Consatti, Santos, Renner & Périco, 2014;Costa,1971; Hanauer, Renner & Périco, 2014; Kittel & Engels, 2016; Renner, Périco & Sahlén, 2013, 2016; Renner, Périco, Sahlén, Santos & Consatti, 2015; Teixeira, 1971). The genus consists of many rather similar species, which makes diagnosis difficult.

  • The Corixidae (Hemiptera) of Oklahoma KURT F
    BIOLOGICAL SCIENCES 71 The Corixidae (Hemiptera) of Oklahoma KURT F. SCHAEFER, Panhandle State Colle.e, Goodwell The Corixidae or water boatman family is a commonly collected fam­ ily taken in a variety of aquatic habitats and frequently at lights at night or on shiny surfaces during the day. Hungerford's 1948 monograph on the world corixids is an important contribution, essential to a serious collector. My paper is an attempt to make the identification of state fonns easier and to supply descriptions and distribution data for the corixids of the state. Schaefer and Drew (1964) reported 18 species and Ewing (1964) added one for the state. Five addi­ tional species are included because information of their known ranges in­ dicates that they will probably be found in Oklahoma when more collecting is done. Each pair of legs is modified for a different function. The anterior pair is short with the tenninal segment (pala) often more or less spoon­ shaped and fringed with bristles for food gathering. Both adults and nymphs feed mainly on algae and protozoa, obtained from bottom ooze (Usinger, 1956). The middle pair of legs, used for anchorage and support, is long and slender, tenninating with two long claws. The hind pair, for swimming, is stouter, laterally flattened and fringed with hairs. The principal dimorphic structures used as key characters are as fol­ lows: males, usually smaller, with vertex of the head otten more produced and frons concavely depressed. Fonn and chaetotaxy of the male palae, front tarsi, are much used characters. The female abdomen is bilaterally symmetrical, while the asymmetry of male may be either to the right (dextral) or left (stnistral).

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

    Proceedings of the United States National Museum SMITHSONIAN INSTITUTION . WASHINGTON, D.C. Volume 121 1967 Number 3569 SOLDIER FLY LARVAE IN AMERICA NORTH OF MEXICO ' By Max W. McFadden ^ The Stratiomyidae or soldier flies are represented in America north of Mexico by approximately 237 species distributed through 37 genera. Prior to this study, larvae have been described for only 21 species representmg 15 genera. In addition to the lack of adequate descriptions and keys, classification has seldom been attempted and a phylogenetic treatment of the larvae has never been presented. The present study has been undertaken with several goals in mind: to rear and describe (1) as many species as possible; (2) to redescribe all previously described larvae of North American species; and (3), on the basis of larval characters, to attempt to define various taxo- nomic units and show phylogenetic relationships withm the family and between it and other closely related familes. Any attempt to establish subfamilial and generic lunits must be regarded as tentative. This is especially true in the present study since larvae of so many species of Stratiomyidae remain unknown. Undoubtably, as more species are reared, changes mil have to be made in keys and definitions of taxa. The keys have been prepared chiefly for identification of last mstar larvae. If earher mstars are known, they either have been 1 Modified from a Ph. D. dissertation submitted to the University of Alberta E(hnonton, Canada. ' 2 Entomology Research Division, U.S. Dept.
